Naturally, all of that reinforced steel and glass makes the
already heavy Range Rover (standard weight: more than 5,000 lbs)
even heavier. But, engineers have retooled the Sentinel's
suspension to compensate for that. The 510-horsepower V8 helps,
too.

There's no point in repelling armor-piercing bullets and grenades
if you can't haul this beast out of harm's way.
